Solar and wind power provide for America the opportunity to strengthen the security of energy supply, jobs in the growing markets and improve the environment. Thanks to breakthroughs in the energy storage systems including the first grid tied solar and storage facility which is closer to potential to reality. The combination of energy storage systems with smart grid technology, utilities can output of power automatically "smooth". This enables intermittent energy sources be available even if the Sun is not or is not the wind is blowing.

In the United States, the American reinvestment Recovery Act is the financing so that 32 demonstration projects, including the large energy storage, smart meters, distribution and transmission system monitoring devices and a range of other intelligent technologies to explore the provision of integrated smart grid systems widely.

Recently, three of these projects for their progress recorded in the development and implementation of energy storage systems. How to extend the worldwide market for clean energy, such projects are continuing the tradition of American leadership in the development of next-generation technologies. See energy blog-post.
